HI ,

     Customer have there question as below.

      1.Dose there have layout guide for ds110df1610?

      2. Whether there have problem if differential output pcb trace longer than 5 inch?

      3.How much driving capability about differential output? 

Thanks

    Hi Brian,

         Thanks for your reply. My customer is very urgent there PCB is pending for this question.

    Could you help to answer bellow  questions. Thanks

     1. Customer already send the gerber files to PCB manufacture , PCB vendor let customer check the differential output trace length,

        Now the differential output pcb trace is almost 5-inch, is it ok?

     2. How much driving capability about differential output? 

     3.Could you give some advice on pcb layout?

    Thanks.

    See my inputs below.

          1.Dose there have layout guide for ds110df1610?

    Refer to Section 10 on the DS125DF1610 datasheet for applicable high -speed layout guidelines

          2. Whether there have problem if differential output pcb trace longer than 5 inch?

    No problem expected

          3.How much driving capability about differential output?

    The DS110DF1610 implements a TX FIR equalization which can apply up to around 12dB of boost. In addition the output amplitude is configurable

    Cordially,
